The replication standard holds that sufficient information exists with which to understand, evaluate, and build upon a prior work if a third party can replicate the results without any additional information from the author

However…
The lexicon of reproducibility to date has been multifarious and ill-defined. The causes of and remedies for what is called poor reproducibility, in any scientific field, require a clear specification of the kind of reproducibility being discussed (methods, results, or inferences), a proper understanding of how it affects knowledge claims, scientific investigation of its causes, and an improved understanding of the limitations of statistical significance as a criterion for claims

😶 We enter data in Excel or SPSS (a.k.a., მონაცემთა ბადის მომზადება) 🤨 We clean data in Excel 😯 We do some data analysis in SPSS 😴 And copy and paste results in Word
All these can be organized at one place, so we can always go back and re-run our analysis
For a long time, the lack of the GUI has been labelled as a main drawback for R users
R-Studio does this job very well.
